Abstract
Time synchronization is a key supporting technology in many applications process of wireless sensor networks(WSNs)
such as the Internet of things
environmental monitoring
target tracking
and so on.The principle of time synchronization technology is elaborated in detail
the model of clock
synchronization error sources are analyzed
and the synchronization protocol classification is introduced.Four kinds of on-demand synchronization protocol are emphatically introduced
take a comparative study on performance of protocol by simulation experiments.
